HARROW.

SPECIFICATION forming part of Letters Patent No. 748,837, dated January 5, 1904.

Application. filed July 20, 1903. Serial No. 166,286. (No model.)

To all whom it may concern,.-

Beit known that I, HU GO A. BRIXEN, a citizen of the United States, residing at Gurnee,

in the county of Lake, State of Illinois, have and it has for its object to provide an improved construction wherein will beV employed a central section suspended from a wheeled frame and outside sections hinged to the central section and suspended at their outer ends from arms which are supported upon the wheeled frame, a further object of the invention being to provide a construction wherein the outer or end sections of the harrow, as also the ends of the arms from which they are suspended, may be folded upwardly and inwardly to reduce the width of the implement, so that its transportation from place to place will be facilitated.

An additional object of the invention is to provide a harrow wherein the various sectionslever.

Other objects and advantages of the inven ered. Fig. 4 is a vertical section taken longi-` tudinally through the wheeled frame and the central barrow section, the lharrow being raised to lift the-teeth above the surface of f the ground. Fig.' l5 is a top plan view of the central section of the barrow, the supportingwheels of the frame vbeing in horizontal section. Fig. 6 is a vertical section taken transversely through the wheeled frame and the central barrow-section in the plane of the ad- -dinal intermediate plate 22. vand 19 project with their ends beyond the justable hanger or post. Fig. 7 is an enlarged section through the portion 26 of the post. Fig. 8 is an enlarged perspective View of the tached thereto.

Referring now to the drawings, the present harrow includes a wheeled frame 10, which may be rectangular in form, as illustrated, or which may have any other convenient shape and which frame is mounted upon an axle 1l, having its ends turned downwardly and then outwardly to form the spindles l2, on which rotate the supporting-wheels 13, which preferably are of small diameter and are provided with broad tires to prevent them from sinking too deeply into the ground. Transversely of the frame lO and against the upper and under faces thereof, respectively, are secured plates 14 and 15, in which is xed a vertical sleeve 17 for a purpose which will be presently explained. Beneath the Wheeled -frame 10 is disposed the central section of the harrow, said central section consisting ot' a front cylindrical bar 18, which lies transversely in front of the wheels 13, additional bars 19, which lie transversely in the rear of the wheels, and other bars 20, which lie transversely between'the wheels, the several bars being parallel and connected by the longitudinal plates 21 and the additional longitu- The bars 18 wheels, while the intermediate bars 20 lie between the wheels, and the plates or sills 21 are bentinwardly or toward each other .between the wheels, so thatL they may receive and support the bars 18 and 19 at points near to the' outer ends of the latter.

This post consists of a lower tubular end to a bar 20 by means of a band 23, which encircles the bar directly adjacent to the intermediate plate or sill 2 2, this tubular postsection extending upwardly through the sleeve on theWheel-frame, hereinbefore referred to, so that when this tubular section of the post is raised and lowered the entire centrai section of the harrow will be correspond-Y ingly moved. 1

upper end of the portion 26 and the parts at- IOO The shifting post or hanger includes also an upper section 26, which is slidaoly mounted in the lower tubular section 'and has a longitudinal slot 27 extending traversely therethrough and through which passes a pin 28, which is engaged with the tubular section, so that the upper section of the post may have a limited sliding movement in lthe lower tubular section. Upon the wheeled frame 10 is mounted an arch 29, having a fulcrumblock 30 at is upper end, to which is pivoted a lever 31, having a bifurcated end which embraces and is pivoted to the upper section of the post, so that when this bifurcated lever is shifted the upper section will have initial vertical movement independent of the lower section, and subsequent movement thereof will serve to raise the lower section and therewith the middle or central harrow-section. To operate the lever to raise the post as described, a hand-lever 32 is fulcrumed upon the rear portion of the frame 10 adjacent to the seat 63 and carries a pulley-wheel 33, a second pulley-wheel 34 being` mounted upon the front of the wheeled frame below the free end of the lever. A chain 35 is attached to the free end of the lever and is passed downwardly and u der the second-named pulley, then rearward-Py through the arch and over the pulley on the hand-lever, and is then taken forwardly and attached to'one of the transverse plates secured to the frame 10. When the hand-lever is operated, the chain is drawn taut and the bifurcated lever, which is attached to the post, is operated to raise the latter. The upper section 26 of the post is bifurcated to form the arms 36 and 37, between which is disposed a transverse beam 38, which projects over and beyond the wheels 13 of the implement, this beam or arm being pivoted upon a bolt 39, as shown. A segmental plate 40 is attached to the beam 38 and extends between the arms 36 and 37 and has a notch 4l in its upper edge. In the upper ends of the arms 36 and 37 are vertical slots 36 and 37', respectively. In the slot 36 is pivoted a latch 42,which is movable into and out of engagement with the notch 4l of the segmental plate 40, and when the latch engages said notch it engages also the slot 37', thus holding the plate 40 and thev beam 38 against pivotal or rocking movement. When engaged with the notch, the latch holds the transverse arm against rocking movement on the bolt 39. At the ends of the beam or arm 38 are hooks 42', which form stops which engage beneath and support the supplemental arms 44, which are pivoted to the main arm in the rear of the hooks. Connected with the free end portions of the arm 38 are chains 45 and 46,which eX- tend down wardly'and are connected by means of bands 47 with the bar 18 and the middle bar 19, so that the central harrow-section is suspended from the chains, as well as from the shifting-post,when the harrow is in raised position, there being sufficient slack in the chains to permit of the entire lost motion of the section 26 of the post before the chains are drawn taut, so that the harrow-section is lifted at its center and at the ends of the said bars 18 and 19 simultaneously.

In connection with the central harrow-section are employed two outer or end sections. Each of these outer or end sections of the harrow consists of longitudinal plates or sills 49, which have transversely-alining perforations that receive transverse parallel bars 48, the structure being braced by the bar 50, that is engaged at its central portion through the central plate or sill and has its ends passed rearwardly and divergently and engaged with the outer plates or sills. The foremost bar 48 of each of the end sections of the harrow is alned with the bar 18 and is connected thereto by a short section of chain 51, while the rearmost bar 48 of each of the end sections of the harrow is alined with the middle bar 19 and is connected thereto by a short chain-section 52, the remaining bars 48 being alined with the bars 2O and the adjacent bar 19, respectively. These chainsections form, in effect, hinge connections between the sections of the harrow, so that the end sections may be folded upwardly, as illustrated in Fig. 2 of the drawings.

To suspend the end sections of the harrow, chains 53 are connected'to the supplemental arms 44 and the chains of each arm are passed downwardly and divergently and connected with the outermost sill or plate of the section, and when the hand-lever is operated to raise the main and supplemental arms the outer ends of these end sections of the harrow are swung upwardly and clear from the ground during the lost motion of the section 26 of the post. When the entire post moves upwardly, both the central or main section and the supplemental or end sections move upwardly, this Vupward movementv being snfcient to draw the harrow-teeth from the ground, so that the harrow may be turned or otherwise manipulated with freedom.

When it is desired to transport the harrow, it is advisable thatits width be reduced, and to accomplish this result the end sections of the harrow are swung into substantially vertical positions, as shown in Fig. 2, they being held in such positions by means of the hooks 54, which are pivoted tothe sides of the main arm for movement into engagement with the rings or eyes 55, carried by the end sections of the harrow.

To the frame 10 is connected a tongue through the medium of hounds 56, and pivoted to this tongue and depending therefrom is a stirrup 57, in which is engaged the reduced end of a tongue 58, which is attached to a draft-bar 59, which is disposed transversely of the middle section of the harrow and is connected to the sills 21 thereof by means of links 59'. Connected to the ends of the draft-bars by means of hinges 62 are other draft-bars and 61, which are con- IOO IIO

nected, by means of links 62, with the front ends of the outermost sills of such end sections, and these supplemental draft-bars are connected with the tongue 58 by means of chains 60', which permit of vertical swinging movement of the supplemental draft-bars with the end sections of the harrow when the latter are folded upwardly to the positions shown in Fig. 2 of the drawings.

A seat 63 is supported upon the rear portion of the frame l0 in a convenient position for the operator, so that he may manipulate the hand-lever which raises and lowers the several sections of the narrow.

The bars of the several sections of the harrow are each provided with barrow-teeth 64. The barrow-teeth of the main or central harrow-section are adapted to'be shifted to stand at various angles to suit dierent specific conditions by rotary movement of the bars that carry the teeth. To accomplish this rotary movement, a lever 65 is fixed upon the middle bar 19, and pivoted thereto is a shift-bar 66, which is pivoted in turn to the ears 67, which are fixed upon and project upwardly from the remaining bars of the harrow-section, so that when the upper end of the handleveris pressed forwardly the bar 19, to which it is attached, is rotatedin a corresponding direction to swing its teeth rearwardly and upwardly, and at the same time the remaining bars are moved in the same direction to similarly carry their barrow-teeth. By thus swinging the bars their teeth will be caused to discharge any trash that. may have been taken up by them, it being understood that the same results may be accomplished in the same manner in connection with the supplemental barrow-sections.

In practice modifications of the' specific construction shown may be made, and any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.
